Re: [mapserver-users] How can I avoid long notation of double values in label or info template for shapes?
For completeness in a template you can use the item tag, e.g.: [item name="foo" precision="2"] There is also a commify option to make big numbers look nicer.

Before I defined LABELITEM mycolumn and got the long notation: 2.540e+000 with definition TEXT mycolumn the label looks fine (without using any function): 2.54 Is there a solution for the query result too?

I got a solution. CONNECTIONTYPE OGR CONNECTION "double_test.shp" DATA "Select *, J_2010_201*1 as newcolumn from double_test" The function round(numbercolumn,2) was not found but with multiplication by 1 it works.

Would be nice if I'm wrong. An workaround could be to use the ogr connection type. This way, you can access and modify your features/attributes with SQL. Look at example #4 here [1]. I think you can use "SELECT ..., round(numbercolumn,2) as mycolumn FROM..." here. But than... if the performance isn't good enough, it might me worth to just preprocess the shape files. Or put them in a database to be more flexibel.

Re: [mapserver-users] How can I avoid long notation of double values in label or info template for shapes?
According to http://www.mapserver.org/mapfile/class.html
TEXT ("Area is: " + tostring([area],"%.2f"))
could also be used.
round and tostring are documented in
http://www.mapserver.org/mapfile/expressions.html
round ( n1 , n2 )
tostring ( n1, "Format1" )

Hello,
I have a shapefile with a column of type double that contains values

When I label the geometrie with this column or display this column in
my infotemplate I get the following notation of the values:
2.540e+000 -2.030e+000
If there a way to tell MapServer to display the "normal" notation of
the value? Or do I have to change the shape?
You can define your own format by using
...
CLASS
...
TEXT (round[numbercolumn], 2)
...
LABEL
...
END
END
...
In RFC 64 [1] you'll find some informations.
I'm pretty sure I used it for myself. But grepping through my current
mapfiles say otherwise. So I can't give an working example.
